Another importantobject of the inventi-on is to provide a device of this character which may be readily and easily installed on knitting machines, eliminating theinecessity of making alterations in the knitting machine construction to'apply the device. 1

lVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in'the combinaticn and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing: Figure 1 is a perspective view disclosing the I machine head, cylinder and needles sup-i Figure 2 is a perspective view disclosing the cam box as removed from the machine head.

Figure 3 is a sectional View taken transversely through the cam box illustrating the relation of the cam with the needles.

Figure dis a front elevational view of the cam and arm supporting the same.

Referring to the drawing in detail, the I) reference character 5. indicates a machine head and the reference character 6 indlcates the cylinder of a knitting machine.

ates, which adjusting screw allowsv the cam box to be moved with respect to themachine head. Y 1

A slot 12 is formed in the cam box and provides aclearance for the cam 13 formed at the free end of the. arm 14 which is secured to the cambox by means of the set screw 15 in a manner to permitof adjust- I ment of the arm 14 towards and away from the cam bar, or cylinder'associated therewith. I

Theneedle butts are indicated at ldand as clearly shown by Figure 3 of the drawings, the cam'13 is adjustedto miss the medium butt needles and short butt needles but contact with the long butt needles t'o draw them downwardly in the knitting of the stocking or sock, allowing thefinger that carries the yarn to drop in and-catch on the medium butt needles after the..cam has forced the long'butt needles downwardly out of action.-

I I 7 An extension 17 forms a part of thearm 1-1 and is supplied "with a threaded opening extending transversely therethrough fori'the reception of the adjusting screw 18 which adapted to contact with the cylinder adacent to the lower end thereof as clearly shown by Figure 3 to move the cam 13-.within the cut out portion 12, to adjust the cam with respect to the needle butt-s.

The set screw 19 operates'through the extension 1'? and is designed to engage the adjusting' screw 18 to lock the adjusting screw against movement after anadjustinent of From the foregoing it will be obvious that as the cylinder rotates during the knitting operation, the butts of certain needles will be engaged by the oamand forced downwardly allowingthe finger that carries the yarn to drop'in and catch on the remaining needles after certain needles have been ulled down out of action.

Should it be desired to adjust the cam so that the long butt needles and the medium butt needles willbe engaged thereby and moved downwardly, the adjusting screw 18 may be moved accordingly to allow the cam 13 to extend into engagement with the methe cam has been made. to cause the cam to j operate on certain needles.

needles.

WVe claim In combination with a machine head cylinder and needles carried thereby, a cam slot, said cam adapted 'to engage needle butts of the machine, an extension forming a' pait of the arm and having a threadect opening, an" adjusting screw extending through the extension and adapted to contact with the cam box to adjust the cam to- Wards or away fromthe needle butts.

In testimony that We claim the foregoing as our own, We have hereto affixed our signatures. I
